CAR.

Specification of Letters Patent.

Patented Nov. 30, 1909.

Application filed August 12, 190B. Serial No. 448,086.

To all whom it muy concern:

Be it known that I, EZRA S. BUCKNAM, a citizen of the United States, anda resident of the city and county of Philadelphia and State ofPennsylvania, have invented a new and useful Improvement in Cars, ofwhich the following 1s a specification.

The ob'ect of my invention is to provide a car wit i suitable windows,each of which is provided with an upper and a lower sash so arranged andconnected that the raising of the lower sash will also raise the uppersash and the two will move together into and out of the roof pockets andalso to provide the upper sash with suitable means for permitting it tobe lowered so that it will have a cert-ain amount of movement while thelower sash is at rest in its lowest position, so that the window may beopened at the top, a desirable feature in interurban trallic where highspeeds are utilized.

This object is accomplished by my invention, one of the embodiments ofwhich is described below.

For a more particular description of my invention, reference is to behad to the accompanying drawings, forming a part hereof, in which:

Figure 1 is a sectional view showing a window provided with myimprovelnent. Figs. 2 and 3 are sectional views taken on the lines 2 2and 3 3 respectively, of Fig. 1. Fig. 4 is an enlarged view of a portionof the structure shown near the line 2 2 of Fig. 1. Fig. 5 is a detailedview showinga portion of the lower sash. Fig. 6 is a sectional viewshowing a portion of the bottom of the lower sash and the parts adjacentthereto. Fig. 7 shows the pintle in the position it occupies when theSashes are raised into the roo-f pocket. F ig. 8 is an enlarged detailedview showing the structure near the line 3 3 of Fig. 1.

Throughout the various views of the drawings, similar referencecharacters designate similar parts.

My improved car window 1 is rovided with stanchions 2 connected by tlieusual window sills 3 and letter board 4, roof 5,

deck rail 6, head lining 7 curtain molding 8 as well as the other partsnot shown, all o which are of the conventional type, except ashereinafter noted. The stanc ions 2 are also provided with the outsideparting strip 9 and the inner parting strip 10, as well as the strip 11which dehnes one wall of the curtain groove 12. The Stanchions 2 alsohave a pintle way 13 that extends from the deck rall G to or near theWindow sill 3 and preferably extends substantially as shown in Fig. 1.This pintle way has holes 14 adapted to receive the bolt 15 which issecured near the lower edge of the lower sash 16 in the conventionalmanner. Below the line 3 3 in Fig. 1 this pintle groove 13 curvesoutwardly and downwardly until in the plane of the sash 16, when itfollows the plane of this sash so that the bolt 1.5 will always resttherein or in the holes 14. This bolt 15 can be withdrawn from the holes14 in the bottom of the groove 13 but not from the groove 13 while thesash 16 is in use so that the sash may be held in any desired position.

The outer edge of the sash 16 is provided with a stop 17 above which isa metal slideway 18 secured to the outer edge of the sash 16 and in thisslideway 13 is mounted the upper sash 19 which is so arranged anddisposed that it can slide freely in the slideway 18 until its movementtherein is limited by the stop 17. Near its upper edge, the sash 16 isprovided with a pintle 20 which may be of any suitable form but ispreferably made as follows. It is provided with a base 21 .secured tothe inside of the sash 16 by screws or other suitable means, and it isprovided with a trunnion 22 on Which is pivotally mounted a slide 23which has a large wearing face that rubs against the inner wall of thegroove 13 so that this pintle will move over said groove with the leastpossible friction and wear and tear, The exte rior of the sash 16 andimmediately below and secured to the top bar 24 thereof is a stop 25which engages a second stop 26 secured to the upper sash 19substantially as shown in Fig. 8. The stops 26 and 25 engage to limitthe upward movement of the sash 19 while the sash 16 remains at rest andalso to cause the lower sash to force the upper sash into its properposition when the window is closed.

The u per edge of the uplper sash'19 1s provide with a suitable bo t 27which 1s adapted to enter holes 28 as shown 1n dotted lines in Fig. il.When the upper sash is so lowered, it slides as stated above in theslidewa f 18.

lirom the foregoing the oieration of my improved device will be reailyunderstood. By withdrawing the bolt 15 from its hole 14 and raising thelower sash from the position shown in Fig. 1 in the full lines to theposition shown 1n the dotted lines this sash is raised vertically andthe slides 18 enga Ic the sash 19. llVhen the two sashes are a reastthey are raised together. When lowered they are also together until thesash 19 is in place when the sash 1G continues its move* ment alone andthe stops 26 and 25 cause the sash 19 to take its proper position whenthe lower sash 16 is in its proper position and the slide 23 forces thetwo sashes to ether so that they are held with a substantial ywatertight joint. By withdrawin the bolt 2T, the sash 19 may be loweredrom the position shown in Fig. 1.

While I have shown one embodiment of my invention it is obvious that itis not restricted thereto, but is broad enough to cover all structuresthat come within the scope of the annexed claims. l

What I claim is:

1. In a device of the class described, a pair of stanchions, each ofwhich is provided with a pintle-way, upper and lower sashes adapted toslide between said stanehions, means permitting the upper sash to belowered while the lower sash is being raised, means for causing thelower sash to either raise or lower the upper sash so that both may bemoved together upwardly or downwardly, and pivotally mounted means forautomatically causing the upper sash to assume its proper position whenthe lower sash is down.

2. In a device of the class described, a pair of stanchions each ofwhich is provided with a pintle-way, upper and lower sashes adapted toslide between said stanchions, means for permitting the upper sash to belowered while the lower sash is being raised, means for causing thelower sash to either raise or lower the u per sash so that both may bemoved togetlier upwardly or downwardly, means for allowing the lowersash to continue its movement alone after the upper sash is closed, andpivotally mounted means for automatically forcing the sashes togetherwhen the lower sash is closed.

3. In a device of the class described, a pair of stanohions each ofwhich is pro vided with a intle-way, upper and lower sashes adapte toslide between said stanchions, means for A)ermitting the upper sash tobe lowered while the lower sash 1s being raised, means for causing thelower sash to either raise or lower the upper sash so that both may bemoved together upwardly or downwardly, means for allowing the lower sashto continue its movement alone after the upper sash is closed, and apivotally mounted slide on the lower sash for forcing the sashestogether when both areclosed.

4. In a car of the class described, a win dow having stanchions ateither side, an upper and a lower sash adapted to slide be tween saidstanchions, the lower sash being provided with a stop and a slideway,the upper sash being mounted in said slideway and engageable with saidstop, means whereby the upper and lower sash are moved downward togetheruntil the upper sash is in closed position and allowing the lower sashto continue its movement alone and rocking means carried by the lowersash for auto matically forcing the sashes together when the lower sashreaches its closed position.

5. In a. car of the class described, a window having stanchions ateither side, an upper and a lower sash adapted to slide between saidstanehions, the lower sash be ing provided with a stop and a slideway,the upper sash being mounted in said slide way and engageable with saidstop, means whereby the upper and lower sash are moved downward to otheruntil the upper sash is in closed position and allowing the lower sashto continue its movement alone, and pivotally mounted means on the lowersash for forcing the sashes together when the lower sash reaches itsclosed position.
